Centre for Mendelian Genomics, University Medical Centre Ljubljana RCV001195917 SCV001366341 uncertain significance D-Glyceric aciduria 2016-01-01 criteria provided, single submitter clinical testing This variant was classified as: Uncertain significance. The following ACMG criteria were applied in classifying this variant: PM2.
Invitae RCV001859181 SCV002259959 uncertain significance not provided 2022-11-01 criteria provided, single submitter clinical testing This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 438 of the GLYCTK protein (p.Pro438Leu). This variant is present in population databases (rs758823918, gnomAD 0.2%). This variant has not been reported in the literature in individuals affected with GLYCTK-related conditions. ClinVar contains an entry for this variant (Variation ID: 930335). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt GLYCTK protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
